Resume a manually interupted mission

Is there any way to resume a mission without landing if you have taken manual control partway through?

I have use sport mode to keep away from birds a couple of times (Mavic). Once I have done so the only option DD seems to give me is a return to home button. Is there some way to resume the mission that I am missing, or is it necessary to come back and land any time you’ve gone to manual control?

Have to land.
You can copy the flight plan and set your starting waypoint to pick up where you left off.

OK, that is disappointing, I was hoping I’d missed something.
